A radio terminal 10 includes a radio communication unit 11 configured to receive packets at predetermined intervals through a first network 100 or a second network 200, a buffer 15 configured to temporarily store packets received by the radio communication unit 11, another radio communication unit 11 configured to transmit a preparation request for handover from the first network 100 to the second network 200, and an application processor 16 configured to reproduce the packets stored in the buffer 15 at a predetermined rate determined according to the predetermined interval. The application processor 16 stops the adaptive buffer control in response to the transmission of the handover preparation request.
